Q. Josiah is saving money and plans on making monthly contributions into an account earning a monthly interest rate of 0.35%. If Josiah would like to end up with $12,000 after 5 years, how much does he need to contribute to the account every month, to the nearest dollar? Use the following formula to determine your answer.A=d(i(1+i)n−1)A= the future value of the account after n periodsd= the amount invested at the end of each periodi= the interest rate per periodn= the number of periodsAnswer:
Identify Given Values: Identify the given values from the problem.A (future value of the account) = $12,000i (interest rate per period) = 0.35% per monthn (number of periods) = 5 years ∗12 months/year = 60 monthsWe will use the formula A=d∗(i(1+i)n−1) to find d, the amount invested at the end of each period.
Convert Interest Rate: Convert the interest rate from a percentage to a decimal. i=0.35%=1000.35=0.0035
Substitute Values into Formula: Substitute the values into the formula.A=$12,000i=0.0035n=60Now we will plug these values into the formula to solve for d.
Calculate Value Inside Parentheses: Calculate the value inside the parentheses.(1+i)n=(1+0.0035)60Use a calculator to find the value.(1+0.0035)60≈1.229678
Calculate Numerator: Calculate the numerator of the formula. ((1+i)n−1)=1.229678−1=0.229678
Calculate Denominator: Calculate the denominator of the formula.i=0.0035
Calculate Fraction Value: Calculate the value of the fraction in the formula. 0.229678/0.0035≈65.6228571
Calculate Monthly Contribution: Calculate the monthly contribution d.A=$12,000d=(0.229678/0.0035)Ad=65.6228571$12,000d≈$182.88
Round Monthly Contribution: Round the monthly contribution to the nearest dollar. d≈$(183)
